Garlic

Almost every Vietnamese dish contains garlic. Look for the small cloves when selecting fresh garlic--these have a sweeter taste. If you have larger cloves, remove the small sprout inside--this sprout makes the garlic taste bitter.
They have a characteristic pungent, spicy flavor that mellows and sweetens considerably with cooking.

In Korea, heads of garlic are fermented at high temperature; the resulting product, called black garlic, is sweet and syrupy, and is now being sold in the United States, United Kingdom and Australia.
